My screen is washed out of almost all color. The menu included. everything works and i can see images


If you've tried by replacing its T'Con bard, and the fault remains as the same, the display panel should be suspected. Contact the authorized service centre for Sharp in this case. It will be the best.

This is usually caused by a defective CCD image sensor and can be repaired fairly inexpensively. However, it's not a user serviceable problem and will need to be repaired qualified service technician.


My name is Rick and I'm a professional repair technician with over 20 years in the business and have repaired many of these.
